42 #SCREW MACHINE - KnKut

The KnKut KK7-42 #42 Short Stubby Length Drill Bit is engineered for professionals demanding precision and durability in challenging drilling applications. Also known as a screw machine length drill bit, its compact design offers superior rigidity, minimizing deflection and breakage when working with tough materials or in confined spaces. Manufactured in the USA from premium high-grade Molybdenum High Speed Steel (HSS) with high vanadium content, this drill bit is built to withstand rigorous industrial and automotive use.

Key Features

• Enhanced Durability: Constructed from high-grade Molybdenum HSS with vanadium content, and salt nitride treated to harden the tool's surface for extended life.
• Superior Rigidity: The shorter flute and overall length design provides increased rigidity, reducing deflection and breakage, especially in high-speed operations.
• Precise Drilling: Features a 135° split point tip that starts on contact, eliminating the need for a center punch or pilot hole and preventing "walking."
• Optimized for Tough Materials: Designed to drill effectively through demanding materials such as stainless steel and titanium alloy.
• Reduced Friction: Gold surface treatment ensures maximum lubricity, contributing to smoother drilling and prolonged tool life.
• USA Made Quality: Proudly manufactured in the United States, adhering to high standards of material quality and precision engineering.

Applications

The KnKut KK7-42 drill bit is an indispensable tool for a wide range of professional applications. It is ideally suited for use in screw machines and CNC machining centers where high-speed, repetitive drilling and precision are critical. Its stubby length makes it excellent for drilling in restricted or tight access areas, as well as for use with right-angle drills. This versatile drill bit performs consistently across various materials, including wood, metal, and plastics, making it a valuable asset for automotive maintenance, industrial fabrication, and general metalworking tasks.
